Be it known that LWGEORGE F. Comme, a

citizen of the United States', residing at Port Huron, in the county of St. Clair and State of Michigan, have invented cert-ain new and useful Improvements in Pneumatic Stackers, of which the following is a. specification.`

Pneumatic stacker chutes as commonly constructed comprise a stump or elbow upon whichv the main discharge chute is telescopically mounted so that the latter may be elevated or lowered as desired, and such chutes are also made in two sections, the outer section being telescopically mounted on the inner so that the "chute as a whole may be decreasedor increased in length to discharge material at desireddistances.

The object of my invention is to dispense With suoli a chute arsindicated and provide a non-telescopic chute capabley of' vertical movement without the employment of a sliding elbow joint, and one by which material may be dischargedfatvarying distances,v all as will hereinafter more fully appear.

In the accompanying drawings. which form a part hereof, Figure 1 is a'side eleva- *tion of a. threshing or similar machine in fragment with a pneumatic stacker embodying my improvement combined therewith;

Fig. a plan of my improved rotary raising and lowering l.device connecting two chute sections, which latter are shown inv fragment; Fig. 3 a longitudinal sectional view on thedottedlines 3 -3 in 2; Fig; 4 a. detail section of the rotary device showing the ball bearing joint therein;l Fig. .5 an end view showing the'sliding hood or deiector which I employ; under plan of a portion of the hood removed. f

In said drawing the portions; majcired 10 the chute with .represent the separator, 11 the stacker fan with outlet 12 leading to the stacker chute, the inner curved portion 13 ot' which chute may be revolubly mounted upon a turn table, as 14, of any suitable construction so that the chute as a whole maybe swung horizontally. Chute section 15 is vertically adjustably mounted upon the outer end of the inner sect-ion 13 by means of an angularly positioned turning device by which -said outer section may be raised and lowered' as desired.

and Fig. 6 an will be readily understood, when a tubuvlar structure is cut at an angle the end there- Iof is4 of elliptical forni, andunder such cir-l cumstances two chute sect-ions such as shown could not be jointed mov'ablyin relation to each otherand the constantl peripheral registry thereof maintained. Iii-order, therefore, to produce substantiallytrue circularity i distort the material somewhat by'forming shallow dents inopposite sides thereof, as at 2,0-21, which enables me to flare the elliptical ends thereof an equal amount-on, top and bottom to cause them to assume a circular formation, and by-such arrangement the area and capacity of the chutfefat this pointare the same a's'at other' portions thereof. In this condition the endsof the chute sections 13, l5, are adapted to. be connected vby means of the movable.jointcomprising the band 25 which is securedto sectionv 15 and the. overlapping band 26 which is securedv to section 13, the connecting portions of said bands forming a ball race,-` in which balls 27 separated by suitable fillersy f may be introduced. through an opening provided with an adjustable cover 27'., andwhi'chball bearing arrangement has a binding .effect upon said I bands. Bands 25, 26, are y provided with suitable brackets 30, 31, in 'which is mounted' a screw threaded crank 3 2 by which the outer section may be rotatably moved on said inner section, and which connection further insures that said bands are at all times securely jointed. Said section 15 may be an integral structure to its outer end' or may bein two sections the outer section 35 telescoping upon and clampedto vsaidsection 15 by a Vsuit-able clamp as 36; The-chuteiin its entirety from turntable-14- vto, its-Router end is curved slightly as indicated in Fig. 1, and the'under-side of itsouterlportion'is cut away for a considerable portion of its length. The sides 37 of this cut away'portion are turned upwardly substantially as indicated in Fig. 6, and in which sides I slidably secure an adjustable deflector or hood comprising collapsible sections 38 the sides of which are upturned to overlap said sides 3T as indicated' in Fig. 5. Said hood is provided with a cord 40 by which the same may be dravfry inwardly to any desired point along the chute, as for instance as indicated by dotted lines in Fig. 1, and preferably near its outer end it has a cord 41 attached thereto which may be run over a suitable guide, as 4.2, at an y desired point sothat said hood of thev abutting ends of'these sections I l 'closely to the upper side of may be drawn outwardly. The hood scc-r tions are normally held in extended position by'cord 44, -as will be readily understood, and are automatically collapsible by means of the spring 45.

In the operation of my improved stacker the chute may be swung laterally on its turntable in any desired manner, and because of its curvature from turntable. to outer end, as indicated-inFig. 1. is highly eflicientin that the natural tendency of the discharging.material is to :follow the upper side of the eliute, and as the longitudinal curve thereof is gradual the material by its momentum substantially clings the chute until it 'is deflected by the movable lio-od 38. whereas in chutes as ordinarily constructed the curve above the turntable is very abrupt. and the chute beingextended on a straight line the material when leaving the elliow and striking the upper side of the chute is delected downwardly so that the oncoming material under varying velocities of theblast is being discharged in more or less irregular masses.

In starting a .st-raw stack the chute is lowered by manipulating crank 32. which causes said chute to move downwardly on an approximately vertical line, and as the straw is being stacked the chute is gradually elevated by reversing the movement of Said crank (lowered and raised positions of the chute being indicated by dotted lines in Fig. 1). As it is necessary to discharge the-straw at various points on the stack near to and distant from the separator the traveling hood is suitably manipulated by the cords attached thereto to be drawn in- Wardly or outwardly to any desiredipoint along the chute, as indicated in Fig. .1, and the deposit of the straw governed there- .by. As will be 'readily understood, the

chute is .being swung laterally in either direction during this operation, `and by controlling the' deflection of the straw by the movable hood I am enabled to accomplish the same results as are attained by the use of telescopic chutes, and by the employment of a simple turning device angularly positioned in thel chute as indicated I am enabled in a simpl manner to raise and lower the chute 11i :1n-approximately vertical plane suflicient for all practical purposes without the employment of a telescoping e5 elbow and the supporting and operating devices ordinarily Iassociated' therewith.

I claim as my invention:

1. In a pneumatic stacker, the combination of an inner and an outer chute section.

two bands one rotatable upon. the other vertically and angularly positioned between said sections@ a bracket on each of4 said bands, and means connecting said brackets whereby one of said bands may be rotated upon'the other to cause one of said chute sections to be raised and lowered in a substantially vertical plane.

Q. In a lpneumatic stacker, t-he combination, of an inner and an outer chute section.

a vertically and angularly positioned rotary joint interposed between -said chute sections, brackets on said rotary joint, and an adjustable crank connecting said brackets to rotate a'portion of said rotary joint 75 to elevate and lower its connected chute section in a'substantially vertical plane.

3. In a pneumatic stacker. a rotary joint.

comprising twobands one rrotatable upon the other and each provided with a bracket,

and means connecting said brackets to rotate .one of said bands upon the other.

4. In a pneumatic stacker, a vertically and Aangularly positioned rotary joint coniprising bands, ball bearings mounted hetween said bands, brackets on said bands. and means connecting said brackets to rotate one of said bands.

5. A pneumatic stacker chute comprising sections` the ends whereof are cut at an angle to the axis of said chute, flared to circular' form and arranged vertically inrelation to each other; circulaivbands connected to said sections and to each. other and each provided with a bracket; and: means connecting said brackets to rotate one of said bands upon the other to vertically adjust said chute.
